Because of the limitation it has, C1 Chart Format is depreciated to C2 Chart Format. Despite that however, Cytoid still supports C1 Chart Format so it's still somewhat relevant. This guide will be mostly a reference than an actual guide.
This will be used as our example for the duration of this guide.
These four lines of text is the Chart Header.
Version - Just ignore it.
BPM - BPM of the music. Let the charting software handle this.
Page_Shift - Scanner shift. The music will be delayed by this seconds.
Page_Size - Page size. Basically it's BPM in terms of page. The formula for this is 240/BPM
These are Note IDs. Just directly below Chart Header.
So in C1 Format, every note is initially a click note, only when certain parameters are met do they change to Drag notes or Hold notes.
For easy understanding, in Note IDs we will divide the chart into 5 columns.
This column acts as the Identifier whether this line is a Note ID or a Link ID.
If the first column is filled with value “NOTE” then this line is a Note ID line. This will be the topic in this section.
If the first column is filled with value “LINK” then this line is a Link ID line. You can get more info on Link ID below
This is the Note ID itself. Recent findings shows that Cytoid charts do not need sequential numbering from top to bottom. But for simplicity’s sake, just left it as it is after exporting. This does however, need to be understood, especially for Cytunity users.
PCTyx enforces the Note ID to be sequential from top to bottom. While unneeded, this is a very great feature of PCTyx. This will make sure the chart is easy to recognize which notes are which and thus also easy to troubleshoot.
Cytunity however does not offer the same benefit. It seems after some extensive editing, Cytunity does not repurpose deleted notes, but instead delete the note ID and used a new one. Even worse, Cytunity may also do not update the old Link ID with the new one. This is the primary cause for Link Break error in Cytunity.
This is note timing. In basic principle, this is what time the note will appear (a.k.a. The “Y” position in the Grid). The number is a simple time (seconds) format. There’s no minutes, or hours, only purely seconds.
Another function is to identify which notes are these when you test play and thus can identify which of the Note ID is used on Link ID. This is mostly for advanced charters who wants to connect drag notes to the next page.
This is the Horizontal position the notes will appear. The “X” position on the Grid.
The value is from 0.000 to 1.000, with 0 being the left most of the screen while 1 is the right most of the screen.
For charters, this column is to identify which Note ID for which notes when the pattern is Double, triple, or quadruple (or more), because all of these patterns use multiple notes in same timings. Mostly only useful to make sure you don’t connect to wrong Note ID when editing Link ID.
This is the Hold notes duration.
Any value above 0 will change the note into Hold note with hold duration being the value you put here.
This is useful if you want to make Super Long Hold Notes that spans multiple pages since Cytoid (Ver. 1.0 to 1.4) does support it, only the visual aid is not perfect.
The format is basic seconds.
If you scroll to the bottom you'll find something like this
This is what we are interested in
The LINK is an identifier that this line is a Link modifier to create drag notes. The numbers beside LINK are Note IDs.
Notes with such Note IDs put here automatically turns into Drag notes. You can connect drags by deleting LINK modifier and moving the note IDs into the drag you want to join.
Like so:
This is essential trick to make multiple pages drag notes.
Note IDs in Link must exist and match on NOTE modifier or else Cytoid will act funny. Cytunity also spat out Link Break error.
